Subject: [fairchildclub] Starting problem


> Hello, All:

> always started. This season, however, it has become yet more lethargic
> and now it barely makes it across the first compression stroke, two if
> Im lucky. My A&P thought it was the old battery wiring, so I did some
> voltage drop tests and discovered I was losing about 2V from the
> battery (+) terminal to the starter motor while cranking; about 1V lost
> from the battery to the master relay and 1V from the master relay
> (through the starter relay) to the starter. Does this seem reasonable?
> I would expect less.

> The next day, after charging the battery, I took some auto jumper cables

> Surprise -- it still didnt crank perceptibly better. Assuming the
